I inferred the attached image to be remaining part of the question that shows the data set.
Answer:
1. Mean for N1= 75
MAD for N1= 0
2. Mean for N2= 124
MAD for N2= 7/5 (1.4)
Explanation:
1. Mean for Neighborhood 1:
Total price value= 750
Number of data set= 10
Mean= 750/10= 75
MAD for Neighborhood 1:
Sum of data set difference from mean= 0
Number of data set= 10
MAD = 0/10
2. Mean of Neighborhood 2:
Total price value= 1240
Number of data set= 10
Mean= 1240/10= 124
MAD for Neighborhood 2:
Sum of data set difference from mean= 14
Number of data set= 10
MAD= 14/10= 7/5 or 1.4
